A portable hydraulic pump is a device that applies both Pascal's Principle and the Principle of Levers. Pascal's Principle states that "when pressure is applied to a point within a fluid contained in a sealed vessel, that same pressure is transmitted through the fluid to every point on the entire inner surface of the vessel." The Principle of Levers is manifested by the use of an extended operating handle, which allows for the generation of high output pressure using a relatively low operating force.
The operational process involves manually driving a plunger to pressurize the hydraulic fluid contained within a closed system [2]. In terms of specific design, the secondary booster mechanism-utilized for the second stage of pressurization following manual pre-pressurization-employs a slider-type screw pump. During operation, the position of the pressurizing handle remains stationary while the pressurizing piston itself does not rotate; this design minimizes friction, extends service life, offers a wide range of pressure adjustment, and ensures smooth, effortless pressure buildup and release.
The device utilizes a circulating secondary filtration system for its working medium, ensuring that the fluid within the pipelines remains clean and resistant to clogging. Furthermore, the equipment is fitted with a high-pressure safety valve, which serves as a protective mechanism in the event of abnormal pressure conditions.
